CLUSTER-SETTING.

SPECIFICATION forming part of Letters Patent No. 630,197, dated August1, 189.9.

Application filed November 29, 189 8. Serial No. 697,941. (No model.)

To @ZZ whom it may col'z'cer: Y

Beit known that we, GEORGE W. DOVER and FRED L. KING, citizens of theUnited States, residing in the city and county of Providence,in theState of Rhode Island, have invented an Improvement in Cluster-Settings,of which the following is a speciiication, reference being had to theaccompanying drawings, which are hereby made a part of thisspecification.

The object of our invention is to produce a cluster-settingfor jewelrywhich may be made from cheap or light-weight stock so constructed as toprevent the easy displacement of the inclosed jewels. This end isattained by the construction shown in the drawings, Where similarletters refer to similar parts throughout.

Figure l is a plan view of the setting-body. Fig. 2 is a perspectiveView of the central member of the setting detached from thesetting-body. Fig. 3 is a view in cross-section along the line fr ofFig. l of the settingbody with the central member of the settingadjusted therein. Fig. a is a plan view of the complete setting with thejewels set therein, and Fig. 5 is a cross-sectional elevation of thesame.

Referring to the drawings, A is the settingbody, cupped up from aplanchet in the usual manner, with holes b b pierced about thecircumference of its base. Oircumferential flutes a a extend upwardlyfrom the base of body A andforrn its periphery. Each flute is surmountedby a point or points c c.

The central member of the setting B is struck with a cup-shaped basehaving projections d CZ. These projections terminate in points e e,whose dimensions regularly diminish toward their ends. At the base ofeach point upon the projections d d are shoulders 7L h, projecting fromthree sides, which form a bearing for the outer stones, in conjunctionwith the central stone.

Weunite the members of our setting by inserting the projections d d intothe openings b b from below until the bases l of the two memberscontact, as in Fig. 3. The points It will be seen that this constructiongives a reinforced setting-base Without the use of solder, givinggreater strength than can be secured in a cheap setting formed from asingle piece of stock, while the shoulders on the inner projectionsform, in conjunction with the edge 0f the superimposed central stone, abearing for the outer stones sufficiently strong to insure the latterfrom displacement.

It will be noted that the jewels or stones constitute means for lockingthe parts of the vsetting to each other, or, in other Words, that theentire assemblage-'to wit, the several parts of the setting and theseveral stones mounted therein are so related as to effect the permanentassociation of the entire article of jewelry. For instance, it will benoted that the central stone extends into the cup or depression of thesetting-body and that its edge is overlapped by the points e e of thecentral member, which is located below the body, and is therefore heldimmovable by the stone, while serving to retain the latter. Furthermore,the smaller surrounding gems supported by the flutings and resting uponthe shoulders 7L of the projections or tongues d are securely locked inplace by the overlapping points c, the inner edges of the smaller gemsbeing located beneath the edge of the central stone.

Having thus described our improved cluster-setting, what we claim asnew, and desire to secure by Letters Patent, is-

l. In a cluster-setting, the combination with a setting-body of acentral member imposed against one side of the body and provided Withgen1-retaining projections extending through the body, substantially asspecified.

2. In a cluster-setting, the combination with a setting-body of acentral member imposed against the central portion of one face of thebody and provided with gem-retaining projections extending through thebody, peripheral projections upon the body and stones having their edgesoverlapped by the projections on the central memberand bodyrespectively, substantiallyas specied.

3. In a cluster-setting, the combination with a setting-body providedwith a depressed central portion and peripheral points, of a eup=shapedcentral member imposed against being provided with projections extendingthe outer face of the depressed portion of the through the perforationsin the first-named body and provided with projections extended memberand provided With shoulders surthrough thev body and provided withshoulmounted by points, substantially as specified. 5 ders surmounted bypoints, substantially as GEORGE W DOVER specified. y Y

4. A cluster-setting consisting of two inter- FRED L' KING' lockingmembers one of which is provided Witnesses: with peripheral iutessur-mounted by points HORATIO E. BELLOWS 16 and with perforations andthe other member SARAH E. LMMIS.
